Each test has 100 questions with four possible answers; just choose the one you think is correct. You have 115 minutes to complete the exam. The clock will appear in the bottom right hand corner of your screen. You need to score at least 85 to pass.
If you just want to study and revise, the tests marked with an A contain the same questions but the test is not timed, and the correct answer to each question will be revealed as soon as you answer. You will still receive a score at the end.
